Tennis is a racket game that has gained a lot of popularity recently. The game can be played against one player or a team of two players can play against two opponents. The objective of tennis is usually to make it hard for the other opponent(s) to make valid returns of the tennis ball. When a player fails to make a valid return of the ball, the other opponent(s) gains more points. On the other hand, the player that fails to hit the ball back does not earn any point.
More focus should not be placed on the game alone but preferably on the technology that is employed to manufacture the tennis balls.
The points below explain in details how to make tennis balls-
1. Knead the Rubber
The first step in making the tennis balls is to squeeze the rubber using a kneading machine. You use natural and synthetic rubbers because the materials have excellent qualities that are vital for the balls. On top of that, synthetic rubber is used because it is long-lasting and improves the bouncing characteristics of the tennis balls.
2. Form Rubber Pellets
Use the compound material composed of kneaded rubber to create pellets that will later make the interior materials of the balls. A cutting machine should be used to cut the pellets into half-shells. Coat the half-shells pellets with an adhesive and allow them to bond tightly under high temperature and pressure. This process is known as vulcanization, and it enhances the chemical properties of rubber.
3. Inject Air Into the Half Shells
Using an air-injecting machine, pump a low pressure into the tennis balls that are manufactured for high altitude areas. On the other hand, inject high pressure into balls that are designed for low altitude areas. The pressure differences ensure that the balls have consistent bounces characteristics in both high and low altitude
4. Bathe the Tennis Balls in Glue
Using sandpaper, roughen the outer surfaces of the tennis balls. A rougher surface is preferred because it gathers and retains more glue. Run the balls through a drum composed of the adhesive compound so that their covers soak adequately with the glue.
5. Apply the Felt Material
Felt is used for covering the tennis balls. Run the two pieces of the dumbbell-shaped felt material through white, adhesive glue and use it to wrap the balls. The process can be done by hand or by using a machine. Higher accuracy is achieved by using hands to cover the balls with felt material.
6. Eliminate Air Bubbles
At this point, take the balls through another vulcanization process that will help in making the bonds between the two halves and those between the ball surfaces and the felt material tighter and firmer.
7. Package the Balls
Dry the tennis balls, test them, and steam them using specialized drying and steaming machines. The balls should then be packed in airtight containers for taking them to the market. It is essential to note that the team logos can be printed on the balls at this point before they are delivered to the teams or to the market.
Understanding how to make tennis balls is critical in helping us appreciate and value the tennis game.
